Let’s  do  some  quick  review:  

Radicals?

Square Roots?

Simplifying  Square  Roots:  

𝑎𝑏 =   𝑎 ∙ 𝑏

To simplify, we will use the ________________________________ with our trusty Perfect-Squares number line:

___________________________________________ Start at the number given in the problem. ________________ each perfect square on the top of the number line until you find a __________ of the given number. Write that number first under a radical. Write _________________________ second under a radical. Simplify _____________ written. (Because it is a perfect sqaure… it will ALWAYS simplify to a whole number!) Examples Simplify the following radical expressions:
